IMPROVEMENT lN BOOK-SUPPORTING ATTACHMENTS FOR TABLES.

Specification forming part of Letters Patent No. 156,304, dated October 27, 1874; application filed June 21, 1874.

To all whom it may concern V Be it known that we, WILLIAM H. PAT- TERSON and OLE SwENsEN, of Oresoo, in the county of Howard and Stateof Iowa, have invented a new and Improved Book-Supporting Attachment for Tables, of which the following is a specification:

The invention will first be fully described, and then pointed out in the claim.

Figure 1 is a sectional elevation of our improved table; and Fig. 2 is a front elevation of the book-holder.

A represents a round revolving table top on a vertically-adjustable spindle, B, which extends up through the center of the top, and carries a bracket, 0, for the support of a bookholder, D E also, an inkstand-holder, F. The spindle B does not revolve with the table, but remains at rest to hold the book-holder directly in front of the writer. The book-holder is adjustable along the bracket by its slotted foot G and the binding-screw H. I is a lampholder at the top of the book-holder, held in advance of it by an arm, J, so as to throw the light of the lamp on the book on theholder to be copied from, as well as the one on the table to be written in. K represents a couple of weighted arms jointed to the book-holder, and hanging down in front of it, so that the weights will rest on the open book and keep it open. The bracket O is attached to the spindle by a socket-piece, L, and a set-screw, M,rcontrived so that it can be shifted around the stand in case it may be wanted to do so, and it can be taken 011' and put on readily forjconvenience in adjusting the parts.

The inkstand-holder is adjustable around the socket on which it is mounted for shifting it about to suit the convenience of the writer.

The vertical adjustment of the table-t0 p and book-holder is efiected by shifting the spindle
